Abstract
An envelope, bag or other mailing device for preventing the shifting of an item located within the envelope and a method for making the same is provided. The envelope includes a front panel, a back panel and at least one protrusion. The back panel is coupled to the front panel to form an interior portion formed between opposed interior surfaces of the front and back panels. The protrusion is coupled to one of the opposed interior surfaces and extends into the interior portion of the envelope. In another embodiment, a second protrusion is coupled to the other side of opposed interior surfaces and extends into the interior portion of the envelope. The protrusions are adapted tp associate with one another to protect items contained within the envelope from external forces and prevent the item from moving around within the interior portion of the envelope.
